The FBI Joint Terrorism Task Force has kept files on activists who expose animal welfare abuses on factory farms and recommended prosecuting them as terrorists, according to a new document uncovered through the Freedom of Information Act.

This new information comes as the Center for Constitutional Rights has filed a lawsuit challenging the Animal Enterprise Terrorism Act (AETA) as unconstitutional because its vague wording has had a chilling effect on political activism. This document adds to the evidence demonstrating that the AETA goes far beyond property destruction, as its supporters claim.

The 2003 FBI file details the work of several animal rights activists who used undercover investigation to document repeated animal welfare violations. The FBI special agent who authored the report said they “illegally entered buildings owned by [redacted] Farm… and videotaped conditions of animals.”

The animal activists caused “economic loss” to businesses, the FBI says. And they also openly rescued several animals from the abusive conditions. This was not done covertly in the style of underground groups like the Animal Liberation Front — it was an act of non-violent civil disobedience and, as the FBI agent notes, the activists distributed press releases and conducted media interviews taking responsibility for their actions.
